What's the best location for a skylight?

I agree with PBB about not placing the skylight near the first reflection points of the speakers on the ceiling. If building codes require placement of a skylight, then you can use diffusion materials rather than absorption. RPG and Echo buster sell these products. ASC and Echo Buster will provide a free evaluation. I received an ASC tubetrap package containing interesting articles on placement of their products. Art Noxon President of ASC sent me the package containing some old stereophile reviews regarding the use of both diffusion and reflection. Another article of interest was on stereophile’s review of Thiel 7.2’s regarding ASC MATT test (you can download this review from Thiel’s website). Jon Risch’s website has a lot of info on DIY acoustic products that really work. He can be found at Audio Asylum – Tweekers Asylum

Best of Luck

A friend of mine recently went with skylights. Very nice to listen to music in natural light.

How big is the room and how large the opening? Perfect rectangle?

His game plan was very simple and we talked about it prior to his doing it. 1) we avoided placing the skylights on angles of direct reflection. You can use a mirror for this. 2) We put a cloth like material on the trim of the skylight light to avoid as many angular hard surfaces as possible to soften the reflected sound on the theory that small omissions (absorbed sound) will be more difficult to hear that some added reflections. 3) The ace in the hole was we added a retractable "shade" over the skylight. It's a light cloth that resembles the old shades you would pull down over a window. If placement and trim measures failed the idea was to simply cover it for "serious listening." (Was there a post some time ago for most anal audio thing you've done/ maybe this is mine, eh?). A short pole pulls the cover over easily. We begged out on making it electric.

Anyway, we cannot hear the difference (as best we can remember) w/ the skylights installed and he almost never uses the shades.

It might be different with other rooms of course and other speakers with different dispersion patterns.

Couple great online sources www.linkwitzlab.com/rooms

www.silcom.com/~aludwig. This has it all and if he doesn't cover it he refers you to who will. He also sites several great online room calculators to use for acoustic treatments.

I remain,

If your ceiling has a pitch to it already..the sonic impact would be limited to the added bounce from the glass. If you have a flat ceiling, the hole down from the skylight would create a waveguide with a reflective surface at the top....and the impact on sonics would be more of an unknown.

From a light/heat gain standpoint, the morning Sun is friendly and the afternoon Sun is less so. ie: solar gain to warm up a room in the A.M. is usually a good thing...esp. if you live in the upper part of the U.S.,..however, P.M. Sun and the solar gain from (ie: South and West facing windows/skylights) are usually a problem in this hemisphere and are a common building error by both builders and Architects.
